Abstract

A rotatable cylinder captures the free end of a new reel of tape for attaching to the end of a preceding reel of tape. The end of the new reel of tape is free for a short length of and then fastened to subsequent layers by an adhesive strip. The free end is guided into a slot in the rotatable cylinder and held in place by a clamp internal to the cylinder. The cylinder clamps the tape within the slot, cuts off the end, and rotates to position the adhesive from the supply reel end of tape into the position adjacent to the end of the tape from the previous web. Winding the previous reel guides the end of the new reel of tape through the tape path. The splicing mechanism of Fig. 1 includes a block 10 which supports the end of the previous reel.

Web Splicing for Threading New Reel Supply

A rotatable cylinder captures the free end of a new reel of tape for attaching to
the end of a preceding reel of tape. The end of the new reel of tape is free for a
short length of and then fastened to subsequent layers by an adhesive strip. The
free end is guided into a slot in the rotatable cylinder and held in place by a
clamp internal to the cylinder. The cylinder clamps the tape within the slot, cuts
off the end, and rotates to position the adhesive from the supply reel end of tape
into the position adjacent to the end of the tape from the previous web. Winding
the previous reel guides the end of the new reel of tape through the tape path.
The splicing mechanism of Fig. 1 includes a block 10 which supports the end of
the previous reel. A clamp 11 holds this end in position for connection to the free
end of the tape 13 from a new supply reel 12. The tape end 13 is secured with a
pressure sensitive adhesive 14 to keep the entire reel from unwinding. A cylinder
15 includes a slot 16 large enough to receive the end of the tape 13. The
cylinder 15 includes a clamp 17 and a rotary cutting device 18. A guide 19
immediately precedes the cylinder 15 as the supply reel 12 rotates clockwise in
the direction of the arrow. The guide 19 has a gradually decreasing gap between
the guide and the reel circumference in order to focus the flow of air through the
guide 19, the slot 16 of the cylinder and into the line 21 which is connec...
